FIELD OF THE INVENTION

The present invention relates to Light Emitting Diodes (LEDs) mounting within electrical and mechanical structures, and in particular to devices, systems and methods for the efficient and inexpensive removal of heat from the LEDs in LED light fixtures.

DESCRIPTION OF THE RELATED ART

LEDs promise to revolutionize illumination, through their ultra efficient conversion of energy into visible light. Within a decade, we have gone from illumination provided by a 60 W incandescent light bulb being replaced by a 13 W Compact Fluorescent Light bulb (CFL) to a 3 W LED light bulb. In effect, reducing by over 90% the consumption required for similar illumination. The above is not only important because it saves energy, but also because now we can illuminate the world without the need to electrify the world.

An LED is an element in which electrons and holes are combined in a P-N semiconductor junction structure by application of current thereby emitting certain types of light. LEDs are typically formed to have a package structure, in which an LED chip is mounted on a mechanical carrier, frequently referred to as an “LED package.” Such an LED package is generally mounted on a printed circuit board (PCB) and receives current applied from electrodes formed on the PCB to thereby emit light.

In general illumination applications, engineers have discovered the importance of generating light in a 360 deg. envelope, not unlike the way in which an incandescent filament illuminates. To accomplish such goals, a new type of package termed an LED sticks or LED straw has been created. In it, individual LEDs are serially placed along a thin sleeve or slice of material, typically made of a sapphire or ceramic material. The stick is powered from each end, creating a stick of light.

In an LED package, heat generated from the LED chip has a direct influence on the light emitting performance and life span of the LED package. When heat generated from the LED chip is not effectively removed, dislocation and mismatch occur in a crystal structure of the LED chip. In effect, brightness is related to power applied, so a large amount of heat is generated in an LED chip due to the high currents, heat that must be typically transferred to a heat sink, typically, a separate device for effectively dissipating the generated heat is required.

LEDs are typically mounted on printed circuit boards (PCBs), which are used to mechanically support and electrically connect the LEDs to electronic drivers (power supplies, amplifiers, etc.) using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive substrate. This substrate is typically a dielectric or insulator. Some of these dielectrics include Teflon, FR-4, FR-1, CEM-1 or CEM-3.

The above has a significant limitation, the thermal transfer from the LED package to the heat sink, is going through a plastic, not the optimal way in which to efficiently transfer heat. What is needed, is a way in which to mechanically support and electrically connect the LED package to a heat sink with the highest efficiency possible.

Referring to FIGS. 1-4, we see the traditional lead frames or lead LED frames 100, which are used today to distribute and ship LED packages 102 (said packages comprised of both lensed LED packages and non-lensed ones) throughout the industry. These frames consist of a lattice 106 having one or more orthogonal horizontal 108 and vertical 110 members that hold the LEDs in place, and are used for shipping from LED mfr. to the LED light fixture assembly mfr.

At the light fixture mfr. site, the LEDs 102 are cut off from the frame strips lattice members 108, 110 and become loose, independent, individual light-emitting diodes LEDs 102. During manufacturing, the LEDs 102 are then soldered onto a printed-circuit board (PCB) 402.

The above has a large number of disadvantages, one of the primary ones being the fact that the already aligned and prepositioned LEDs 102 are loosened, before being re-attached to the PCB 402. This step requires machinery to align and position the LEDs 102. The proposed solution described here is to completely eliminate the PCB 402 used to position the LEDs 102 by making certain changes to the Lead LED Frame (LLF) 100 when manufacturing the LEDs 102. In the traditional method the LEDs 102 are first stamped out, pressed from plastic, electrical and other holders made, crossing points, etc. cut off and then the LEDs are created, then cut off from the frame 100, sorted, aligned and then soldered to PCB.

Referring to FIGS. 5-11, we see the present lead frame arrangement 502 vs. the proposed new 602 LED connector or chain and manufacturing method in a proposed embodiment. In the present method (intended for a PCB line), one or more LED 102 electrical contacts are formed on either side of the LED package 102 (side one 504 and side two 506). These are the electrical leads used to power the LED, which are later bent for surface mount attachment to the PCB). The LED is held to the frame by the LED holders 508, 510 which are usually on two remaining sides of the LED package. These are used to hold the LED package to the lead frame, and are later cut-off after the LED 102 is manufactured.

In one embodiment of the present invention 602, the LEDs 102 are rotated 90 degrees in the design for the forming machine, so that the one or more electrical contacts 604, 606, 608, 610, 612, 614 are formed along each side forming the rows of the lead frame (and between neighboring LEDs), and the LED holders 508, 510 (not electrically connected to the LED) are extended along the column to provide support for the inner members. In one embodiment, the LEDs 102 are connected as a long single-pearl string 902, by a joint 904 between each LED 102.

Power is applied at one end, and flows along the row to power each LED 102 by a suitable power source. After so many LEDs, the LED chain may require electrical ending. However a light fixture formed by a chain of LED chains (say a supra chain) formed by the mechanical linkage of two or more LED chains, with separate electrical power connections going to the various LED chains integrating the supra chain. If required, resistors and other components may be stamped along each or every so many of the LEDs 102 joints 904.

In another embodiment, the individual LEDs 102 are assembled or stamped into a two dimensional matrix 702 in which the rows 704, 706, 708 share the power connections (an LED matrix formed of LED chains). As before, the connections between neighbors along the rows are connected through traditional metal stamping techniques, and may include resistors and other components placed at either the ends or after a number of LEDs. The electrical power connection is attached at either end of a number of LEDs on a column, and daisy chained along the row of the matrix. Resistors such as these are typically used as current limiters to prevent against overdriving of the electronics. Within the columns (i.e. up/down), the LED leads are left uncut, so that within two or more neighboring rows of said LED chains, at least one said LED package occupying the same respective column position within said matrix has at least one of said package upper and/or lower LED lead connected to its respective counterpart above or below it within said matrix.

As before, for electrical reasons the above matrix may be powered column-wise (with the power supply connected along the LED's occupying the first and last columns), or as a supra chain (where the end of each matrix row) is electrically connected to the beginning of another row within the column. Said LED matrix may then be bent into tube, squares or any other suitable shape.

In one embodiment, the LED holder leads 508, 510 (described as upper and lower in reference to the left/right of the power connectors within each LED package) are not cut or clipped, but instead formed as clips, clamps and/or springs along its length or at/near their end 710, 712 so as to mechanically and thermally attach the LEDs to the heat sink 1000. While electrically isolated through either special coatings or encapsulation, they are thermally connected to the LED 102 package, so that efficient, metal-to-metal heat transfer channels are provided. Note a further advantage of this approach, is that these holder leads 508, 510 act as radiating heat sinks.

For non-open collector diodes, the above allows for the voltage connections 602 (as well as 604, 606, 608, 610, 612, 614 and any others) to be held above the datum plane of any heat sink, allowing for the insulation of air to keep voltages from mixing or short-circuiting. Such an approach affords the opportunity to build an electrically connected electrical lead frame with no PCB that is capable of operating in a similar way. In an alternate embodiment, the electrical insulation of the voltage channels (714,716) is accomplished by elevating these above the datum of the heat sink 402.

In alternate embodiments (FIGS. 12-13) such a linear ‘necklace’ or LED strip 1202 is formed when all LEDs 102 are connected through traditional technological interconnectors and holders capable of manufacturer through traditional precise micro-molding injection. In one such embodiment, an encapsulated electrical connection 1204 instead of the PCB carries out the electrical interconnections and mechanical holders between LEDs 102. In such a connection there is no soldering, and all connections represent monolithic, isolated electrical links within an insulated housing.

The plastic housing 1302 of the LED 102 may be configured so that the snap-on of the plastic creates the electrical connections between LEDs 102, which greatly increases reliability and durability of contacts between packages 1304, 1306, 1308, transitional electro resistance decreases because of no soldering points.

Referring to FIGS. 14-15, we see the difference between the LED 102 package attached to the PCB or heat sink 402 by solder 1402, versus the new approach wherein in one embodiment, the connection between the various LED packages 102 is accomplished by wires 1502. Of critical importance is the fold in the connection between LEDs, which is formed as a S or Z or fold in one embodiment, allowing flexible bending of the connection between LEDs.

Referring to FIGS. 16-17 we illustrate a PCB-less system as part of a fluorescent bulb replacement for the T-5 and T-8 bulb standards. As can be seen, the LEDs may be arranged linearly or in matrix form. It should be noted that the lack of a PCB provides for a much wider angle of light (as the PCB does not cause a shadow).

Referring to FIGS. 18-21, we see an embodiment where three or more parallel strips 1802 of LEDs are formed into an LED matrix that may be then shaped cylindrical form or LED roll 1902 and powered from one end to the other. The flexibility stated before, can be appreciated in an embodiment where the LED roll 1902 is fitted inside the body of a traditional light bulb or lamp volume 2202 (FIG. 22) is used to provide Omni-directional light. In an alternate embodiment (FIGS. 23-24), the LED roll is shaped as a tapered cone, improving the light distribution.

In an alternate embodiment (FIG. 25), a flexible matrix lattice arrangement 2502 is curved to fit within the contour of the bulb, lamp or a linear package. Note the driving electronics may be located within the base of the bulb 2504.

In an alternate embodiment (FIG. 26), the LED roll 1902 is formed and inserted within a tube (such as a T-5/T-8 or other similar extended tube), so that they may replace a fluorescent tube within such a light fixture. In one an alternate embodiment (FIG. 27), one or more strips 1802 are inserted within one or more slots 2702 built into said tube 2704 or they may be formed into a LED tube or cylinder 1902 and then inserted into the enclosure tube 2704.

Said enclosure tube may have the aforementioned slots 2702. Note that in all enclosure cases, i.e. bulbs, lamps or the T-5/T-8 tubes 2704, there could be introduced into the enclosure space a gas mix. Besides a gas mix, the complete lighting package may be immersed in a cooling fluid, which may be a dielectric to preserve electrical integrity while providing cooling. Such fluids may include inert gases.

Referring to FIGS. 28-29, we see a single strand LED chain 1202 which in one embodiment we mount to a mechanical strip 2802 with a series of openings that match those of the string 902. The strip acts as both a mechanical holder, and a heat transfer device for the LED packages.

When used in a T-5 or T-8 fluorescent bulb replacement fixture, the ends of the strip 2802 are bent (in one embodiment as an ‘S’, ‘Z’, or any other “spring” form 3002, in order to form a compression spring insert, so that when the strip 2802 is slid within the housing of said tube 2704 it forms a constant and efficient metal-to-metal heat transfer medium to the housing, which acts here as the heat sink. Note that in effect, as mentioned before, the strip 2802, the spring 3402 and insert legs 3404 act themselves as radiators.

When using open-emitter LEDs, it becomes necessary to electrically insulate the bottom of the LED package 904 making contact with the heat sink 3002. One solution would be the addition of a simple FR4 sheet or other electrical insulator ‘sandwiched’ between the bottom of the LED and the heat sink. The different heat transfer rates would be accounted for by the sliding, as there would be no wave solder joints at the LED to crack.

In another solution, as discussed in Zykin (U.S. patent application Ser. No. 13/313,129) and incorporate herein in its entirety trough reference, a base 2902 incorporating a layer of a material such as CERATOM 912 could be used. Acting as an efficient heat conducting dielectric, this would ensure efficient heat transfer to the heat sink 3002 and any fins or radiators attached thereto.

In another embodiment FIGS. 32-33, the LED matrix or grid is held above the heat sink, using only the edge 3202 connections to transfer the heat, resulting in an inexpensive, non-PCB solution. In all cases, the complete lighting package may be immersed in a cooling fluid, which may be a dielectric to preserve electrical integrity while providing cooling. This may include inert gases.

Referring to FIG. 34 we see an alternate embodiment where two or more LED strips 1802 are placed one over the other (forming a bottom LED strips 3406, in one embodiment with lensed LEDs, although in an alternate embodiment they may not need the lensing), the strips of LEDs may then be inserted into a suitably modified T-5, T-8 or other suitable enclosure tube 2704. Said enclosure tube may have the aforementioned slots 2702 or be smooth and have the leads 3402 from the LED strips 1802 bent so they extend outside of the strips without significantly occluding the light emitted from the LEDs. Thus in addition to serving as a thermal radiator, they mechanically support the LED strips 1802 within the enclosure tube 2704.

Referring to FIGS. 35-37, the coating of yellowing phosphor described above may be applied near the periphery of the encapsulation 3502, above the actual LED die area 3602 or directly above the LED die on a traditional package 3702.

Example 1

An LED light emitting bar, pole, filament, or candle could have a size of bar that is plastic covered in length of 30 mm, diameter of 2.5 to 3.5 mm, having a size of bar with connectors of 38-40 mm. In such an example, the quantity of light chips 200 within a single candle could be 26 pcs, in the 465-475 nm, having a serial connection.

It could be mfd. using flip chip technology, having a working voltage of 70-90 Volts, with current up to 30 mA, with a pulse of up to 100 mA. The LED chip size(s) 10×18, 10×20, 10×23, 10×26 mm, depending on the pad size being used. Some additional LEDs could be 10×18 or 20×20 mm with ESP. Thickness of LED die sapphire substrate in the 200 -430 micron (0.2-0.43 mm). Thicker may be better (say −0.43 mm) as a standard for sapphire wafer. Each chip seats on it's own pad —“leg”, having no reflector on the pad.

Top attach, using an eutectic placement, wire bonding: Au or Al with Au plated-chipper. Wire bonding: could be done by 1 wire to LED die, or by 2 wires on same LED die “Leg” size of L 5.0×W 0.7×T 0.7 or L 5.0×W 0.5×T 0.5 mm. LED die “Leg” goes throughout of plastic for 3.0-4.0 mm.

Type of plastic (Epoxy) cover: LED compatible, phosphor compatible, no need for weather protection, bar will be insulated inside and protected Plastic (Epoxy): mixed with phosphor, molded over metal “legs” with LED dies Plastic (Epoxy). Especially shaped for better light output and distribution, cylindrical stars. Microscopic view: bar inside, single wire bonding, eutectic die attach, die thickness ˜10 mil

In one embodiment, the system could be used as replacement for incandescent light bulbs filaments, since due to its shape it could also be used as replacement for “gas discharge line” in T8, T5 fluorescent tubes. There is no need for PCB (Printed Circuit Board), and the separated, independent heat sink for every LED die (chip) in a bar would provide one of the best heat dissipation ability for LED dies, due to the ratio of sizes between LED die and size of the heat sink.

Very low thermal resistance between LED die and heat sink, to ambient, due to eutectic bonding process. Very wide angle of light distribution, due to a shape of pad for die attach, of plastic (epoxy) lens. No needs for secondary optics, lens are molded at the same time of production. Possibility to make heat sink electrically insulated, by using different die attachment methods.
